utility of precomplexation to LiClO(4) as a stereocontrol tactic. The capability of 3 to coordinate to alkali metal ions was quantified. The conformationally restricted nature of this ligand conveys high selectivity for binding to lithium ion. Beyond that, the ionophore prefers to form 2:1 complexes with Li(+) and exhibits little tendency for 1:1 stoichiometry. These properties are shared by the "dimer"

[structure: see text] Preparation of the first rigid homoditopic tris(tetrahydrofuranyl) ligand with a pair of exotopic binding sites specifically tailored for effective coordination to lithium ions is described. The crystallographically defined structural parameters of the monomeric building block and a 1:2 complex of the dimer with lithium picrate reveal the unique features of these materials.
